A few months ago my OBI requires a reboot to receive or make calls. I usually don't notice until callcentric emails my voicmail and the phone didn't ring. A reboot takes care of it.
Today I tried to reboot over the web, and I couldn't access my static IP. I dialed *** and it told me the correct IP. I rebooted ***9 and can make calls again.
TLDR; my obi used to work great, now I need to reboot every few days to make/receive calls.
Any ideas?
